H5Part development and discussion

["Matthew Bettencourt" <mbetten AT sandia.gov>]

Hi, I am getting started writing H5Part files and I am using hdf-1.8.8 
and h5part-1.6.5.

When I run a very simple code, attached, I get an error in the 
H5PartOpenFileParallel which looks like it is an MPI_File_open error.  
However, in my test code I can open a MPI File just fine.

So, this works,
  MPI_File_open(MPI_COMM_WORLD, "foo.mpi",MPI_MODE_CREATE , info, &fh);
but this doesn't
  h5file = H5PartOpenFileParallel("foo.h5",H5PART_WRITE,MPI_COMM_WORLD);

This is beyond my ability to figure this out.  Any help would be great.  
This is on a RHEL-6 machine with openmpi-1.5.3-3.el6.x86_64 and 
gcc-4.4.6-3.el6.x86_64

Thanks
Matt
